I actually wouldn't mind trading Beli, Ayres and Daye (all expirings, plus Daye can be bought out for savings of $750k) - $5 million of salary going out, along with the first rounder, to a team on the rebuild for the right piece coming back on a longer contract.
I trust the front office knows what it's doing. Tons of flexibility heading into the offseason with no albatross contracts to contend with. Can bring the whole gang back together if it wants, or if Mills prices himself out, spend that money elsewhere. Worst case, they'll have around $4 million of cap room (if Diaw signs at $5-$6 million) plus the small midlevel to bring in someone to replace him.
